Until very recently, I remember seeing in the ISU entrant list only 2 Chinese pairs entered with the rest as substitutes. Why it changed to 3 pairs allowed, I also don't know. There is nothing I could find in the ISU rules that would account for granting the Chinese an extra place, unless it is some obscure regulation or loophole that isn't well publicized.

The ISU should put something out there on why this was allowed. The silence from all the other federations is curious, which leads me to believe that all of them know something that we don't. I'd hate to have to go back to my default position, which is that Chinese (sports federations) will always push the rules and even cheat, if given half the chance and other people let them.

OMG！Did Sui and Han throw a 4S? That's HUGE！！！！！
Just like this pair, Sui is SO CUTE! Hope Han can be a little bit bigger and higher in the future, now seems that he's too short ( ISU says that he's only 170cm)
Hope they can hit a 4F next time as they can always give the huge throws!

Sui/Han are absolutely adorable! I really like their expressive personality during their performances, not emotionless, all about tech.
Hope Han can grow a bit more, and Sui not out grow Han... like what happened to Z/Z.
